The projector remote will not let me control the Keynote presentation?
A Keynote presentation responds to a mouse click to advance slides. If your remote has mouse functionality (i.e. Conductor, Executive Plus remote) and you have the USB cable connected between the projector and computer, you can control your presentation with the remote. If your remote has only PowerPoint functionality (i.e. backward/forward, next/previous buttons), then you can’t control the presentation with the remote. In this case, you need to purchase a third-party wireless mouse or use your keyboard/mouse.
